The Effect of Right Colon Retroflexion on Adenoma Detection: A Systematic Review and Meta-analysis.

ABSTRACT:

Background

Although colonoscopy with polypectomy can prevent up to 80% of colorectal cancers, a significant adenoma miss rate still exists, particularly in the right colon. Previous studies addressing right colon retroflexion have revealed discordant evidence regarding the benefit of this maneuver on adenoma detection with concomitant concerns about safety and rates of maneuver success. In this meta-analysis, we sought to determine the effect of right colon retroflexion on improving adenoma detection compared with conventional colonoscopy without retroflexion, as well as determine the rates of retroflexion maneuver success and adverse events.

Methods

Multiple databases including MEDLINE, Embase, and Web of Science were searched for studies on right colon retroflexion and its
